INTERFACE DESCRIPTIONS
I
2
C INTERFACE
All control and access to both EEPROM memory and the RDAC
registers are conducted via a standard 2-wire I
2
C interface.
Figure 2 shows the timing characteristics of the I
2
C bus.
Figure 16 and Figure 17 illustrate standard transmit and receive
bus signals in the I
2
C interface.
